MATTHEW F. BAYER, 0F KENOSHA. WISCONSIN, ASSIGNOR TO SIMMONS COMPANY,

OF KENOSHA, WISCONSIN. A CORPORATION OF DELAWARE CRIB-LOCK.

Specificationof Letters Patent. Patented 1 15 1921 Application filed September 15, 1919. Serial No. 323,689.

To all whom it may concern:

Be it known that I, MATTHEW BAYE a citizen of the United States residing at Kenosha, in the county of Kenosha and State of Wisconsin, have invented certain new and useful Improvements in Crib- Locks, of which the following is a specification.

My invention relates to improvements in tion; to provide a construction which shall be simple in design and economical to manufacture, andln general, to provlde an 1mproved construction of the character re- V ferred to.

In the drawings which illustrate my invention as applied to a childs crib in which the side is capable of being raised or depressed,

Figure 1 is a side elevation of the crib;

Fig. 2 is an enlarged side elevation of the locking means and associated parts;

Fig. 3 is a section taken on the line 3-3 of Fig.2;

Fig. 4 is a section. taken on the line 4-4 of Fig. 2;

Fig.5 is a perspective View of the slotted bracket with which the lock pin cooperates; F ig. 6 is a side elevation of the rod foot;

Fig. 7 is a section taken on the line 7-7 of Fig. 6;

Fig. 8 is a section taken on the line 8-8 of Fig. 6; and

Fig. 9 is a section taken on the line 99 of Fig. 6.

Referring to the drawings, it will be observed that the two-corner posts 10. at the front of the crib, constitute the supports for the movable frame part, or side gate 11, said gate comprising tubular top and bottom rods 12 and 13 and vertical filler tubes 14, the respective ends of which are secured in or to the top and bottomrods 12 and 13 in any suitable manner.

The end filler tubes 15 and 16 inclose the guide rods 17 and 18, the lower ends of which are positioned by the arrangement shown in Figs. 6 to 9 inclusive; In said figures it will be seen that I secure to the bottom of the crib post a. small bracket 19, the securing be- 'ng e1 ected in any suitable manner such as ivets 20. The bracket 19 has at its lower end an outstanding horizontally extending lug 21 which is perforated as shown best in Fig. 8 to provide a comparatively narrow outer slot 22 with an inner circular enlargement 23 of sufiicient diameter to admit the unreduced cir ular end of the guide rod 17. Adjacent to the lower end of said guide rod 17, I out a rectangular notch 24 in the side of the rod thereby reducing its cross section sufiicientiy to enable the notched part of the rod to enter the comparatively narrow slot 22 in the lug 21.

One of the objects of the slot 22 is to permit-a limited amount of movement of the lower end of the rod to or from. the post thereby preventing the rame member 12 from cramping due to possible variations in the dimensions of various parts. The bottom end of the rod 17 is, nevertheless, normally prevented from moving into the enlargement 23 by reason of a small sheet metal stamping 25 perforated to fit loosely around the rod and having a pair of turned down spring lugs 26 to prevent said stamping from rotating on the lug 21 and also to hold the stamping itself against accidental upward movement away from said bracket.

It will be understood that the lugs 26 are formed with sufiicient spring to snap over the bracket lug 21 so that said washer will be secured in so far as vertical movement is concerned.

The distance between the inner edge of the stamping 25 and the outer face of the vertical portion of the bracket 19 is such that the rod 17 is not permitted to enter the enlargement 23, but when it is desired to detach the guide rods 17 for shipping or any other purpose, the washer 25 is raised on the rod above the top edge of the vertical portion of said bracket 19 whereupon the rod caenter the enlargement 23 and may be removed. Preferably a soft rubber collar 28 is placed around the guide rod on the top of the plate 25 to act as a cushion or a noise preventer when the gate is lowered.

The top and bottom tubes 12 and 13 of the gate 11 are drilled out large enough to r a slotted bracket 30 secured to the upper end of the post of the crib, said bracket comprising an intermediate part 31 by which it may be secured to the post in any desired manner and 'an'upper' lug32 and lower lug 33. In the present instance the intermediate portion 31015 the bracket is united to the post 10 by means of a screw 34: passing through the post an d' threaded into said part 31 and a pin 35' which prevents the bracket from twisting out of its position.

' The upper lug 32 constitutes a pivotal bearing for a link controlling the transverse movement of the "upper end of the guide rod 17, said link in the present instance comprising a bent portion 36 of the upper end of the rod, the extremity of said part 37 being bent down parallel with the rod to enter an aperture 38 drilled in the horizontal upper lug 32. Theouter end of the lug 32 is extended as shown at 39- in order to form a stop which,

as shown best in'Fig. 3', limits the outward movement of the upper end of the guide rod. The inner side of the lug 32 is also provided with a bent-up ear 39 which limits the inward movement'of the guide rod. It. will be observed that the stops 39 and 39 are in effeet symmetrically disposed with reference to the pivot so that the guide rod is the same distance from the post in either position.

The lower lug 33 of the bracket 30 is bent to form a right angle part with a depending extension 40, the lower end of which is shaped to form a sloping cam surface 41 so located as to be engaged by the'pin when the'crib side is raised vertically. The pure pose of'said cam surface 41 is to cause the locking pin to travel in a' path behind the edge of the lug 33 when the crib side is raised. It will be manifest that during such cam controlled movement of the upper end of the crib the link 36 will swing into the dotted line position shown at 4.2 in Fig. 3. After the crib side has been raised sufficiently to enable thelower edge of the pin 28 to clearthe upper edge of the horizontal portion'of the lug33, the top of the gate may be pulled outwardly, z. 6., toward the aperture so as .to cause the locking pin 28 to drop through the opening or slot 13 into the looking slot 14; which is a continuation of the upper slot or opening 43.

It will be understood that the described details of, construction are merely illustrative of my invention, the scope. of which should be determined by reference to the appended claims, said claims to be construed as broadly as possible consistent with the state of the art:

I claim:

1. The combination of a post provided with a substantially vertical guide, a gate having its lower end slidable on said guide and havingv an upper part capable of movement relative to said post, interengaging means respectively carried by said post and said up-. per partcontrolled by relative transverse movement of the post and said upper part and a link connectin said post and said upper part for controlling the said transverse movement. 7 I t 2' i 2,111 combination, a support,'a frame member slidably arranged with reference to said support but capable of a limited amount of movement transversely of said support, interengaging means respectively carried by said support and frame member operable by said relative transverse movement of said support and frame memberand a link pivot ally mounted on said support and connecting said frame member to said support for limiting the said transverse movement.

3. In combination, a support, a frame member slidably arranged with reference to said support but capable ofalimited amount of movement transversely of said support, interengaging means respectively carried by said support and frame member operable by said relative transverse movement of said support and frame member and a link pivotally mounted on said support and connecting said frame member to said support for limiting the said transverse movement, and stopping means. for preventing outward swinging movement of said framemember. at. In a crib the combination of a post, a guide rod having its lower end stationarily mounted with reference to said post and having its upper end movable transversely with reference to said post, a crib side slidable on said rod, and cooperating means respectively carried by said crib side and said post for locking said crib side to saidpost in an upper positiotn, said means being disengaged upon relatively transverse movement of said crib side and said post, and a link connecting the upper end of said guiderod with said post to limit said transverse movement. In a crib the combination of a post,

aguide rod substantially'parallel with said post and anchored thereto at its lower end,

7 a crib side provided at its upper'and lower ends with means slidably. engaging said guide rod,a bracket secured-to said post, a link connecting said bracketwith the up per end of said guide rod and cotiperating side subsequent to upward movement thereof, said link limiting said trapsverse' movement.

6. In a crib the combination of a post, a guide rod substantially parallel with said post and anchored thereto at its lower end, a crib side provided at its upper and lower ends with means slidably engaging said guide rod, a bracket secured to said post,

a link connecting said bracket with the upin per end of said guide rod, and cooperating side subsequent to upward movement there- 15 of, said link comprising an integral projection on the upper end of said guide rod.
